Fix preferred size of the Window with a layout

Browse source 
A few problem:
 - the horizontal and vertical property were swapped
 - The implementation of the "preferred_xxx" property was not materialized properly
   because the `bindings` were borrowed in the materialize_fake_properties pass
 - Since the Window has a stretch factor of 0., the preferred size of the inner layout
   was not taken into account when merging the LayoutInfo.  I believe taking the
   maximum preferred size is the right solution when merging them.
